Beta 15:

- autoconfig emulation update, fixes AR3 (broken) autoconfig code that detected non-existing ram expansion at 0x00600000-0x009ffff
- modified directdraw fullscreen mode fallback code
- Picasso96 hires hardware sprite problem fixed. It was emulation problem after all.. (I really need new brown paper bag soon)
- Picasso96 hardware sprite resolution switching problem should be really fixed now. (lots of logging can still happen after alt-tab, this will be removed later)
- disk insert/remove tweak
